[Docs] Fix broken autorefs cross-reference in TurboQuant v2 docstring

[hmellor]

Purpose

The docs build emits exactly one WARNING, from the triton_turboquant_decode_v2 module docstring:

WARNING -  mkdocs_autorefs: api/vllm/v1/attention/ops/turboquant_soa/triton_turboquant_decode_v2.md: from .../triton_turboquant_decode_v2.py:3: (vllm.v1.attention.ops.turboquant_soa.triton_turboquant_decode_v2) Could not find cross-reference target 'j'

The docstring writes pair_table[i][j] unquoted. Markdown parses [i][j] as a full reference link (text i, reference j), mkdocs-autorefs then tries to resolve j as a cross-reference target and fails. Wrapping the expression in backticks makes it render as code, which is also how the same construct is already written elsewhere in the codebase (e.g. `blocks[i][j]` in vllm/v1/core/kv_cache_manager.py).

Docstring text only, no functional change.

Not a duplicate

Checked with:

gh pr list --repo vllm-project/vllm --state open --search "autorefs cross-reference docstring"
gh pr list --repo vllm-project/vllm --state open --search "turboquant"

No open PR touches this docstring or the autorefs warning.

Test Plan

Full mkdocs build before and after the change, with all output captured (not just the tail).

Test Result

Before (on upstream/main @ 52be12cfac):

$ grep -c '^WARNING' build_before.log
1
$ grep '^WARNING' build_before.log
WARNING -  mkdocs_autorefs: api/vllm/v1/attention/ops/turboquant_soa/triton_turboquant_decode_v2.md: ... Could not find cross-reference target 'j'

After:

$ grep -c '^WARNING' build_after.log
0
INFO    -  Documentation built in 398.40 seconds

pre-commit run --files vllm/v1/attention/ops/turboquant_soa/triton_turboquant_decode_v2.py passes.

No model evaluation is included because the change is confined to a module docstring and cannot affect output, accuracy, or serving.
